Power cord length?

I owned the most expensive MIT powercables. These days I know they are not the best anymore. The make instruments and voices too big in proportion. And yes longer powercables often sound better than shorter ones.

5ft is the optimum length.

What is the opinion of those here on this thread?, Regarding the question, what is the sound difference between a 3ft, 5ft, 6ft, power cord?, Is it the presatation?, meaning, forward presatation-A,B,C, seating role from the stage of a musical event?, sound stage seating of H,I,L seating role from the stage of the musical event, which I prefer, sounds more believable, Does these specific Lenghths change the tone?, Will one lenghth give listener fatigue over the next lenghth?, answer the differences period you can hear between 3ft, 5ft, 6ft, power cords to the best of your knowledge, I look forward to the answers, cheers.

In the beginning Nordost sold only starting from 2 metres. After we tested a few 1 metre cabels I understood why.

But....beging commercial they started selling there powercabels also from 1 metre. How stuppid you can be.

The dynamics were better of the longer cables. Also the mid freq. had more boduf and sounded more natural.

In general a longer powercable is Always better in the lowest freq. When we gave a client a 1 metre and 1.5m version. Most of the time the bought the 1.5m version.

I suspect the only thing one could bank on and worth the worry is make it long enough to reach the outlet.
